Ability State and Notifications -This allows user code/blueprints to respond to state changes. -These values always reflect the latest simulation state -StateChange events are just that: when the state changes. They are not emitted from the sim themselves. -This means they "work" for interpolated simulations and are resilient to packet loss and crazy network conditions -That said, its "latest" only. There is NO guarantee that you will receive every state transition
